Heater core replacement, 93 corsica. Ive read more than one source that says the dash does not have to be removed, but you just need to do thru the panel in the center below the dash. At least two sites Ive read say the same thing. Anyone here who has done it and can toss out a little more information? Thanks

Hope this helps you ??

Locate teh heater/AC air exchange box and you can oprn that by removing all teh screws around the out side edge to open it and get to the core that way. I am usually able to access them from under teh dash without ever removing the dash but that will depend on the actuall installation.

YOU NEED DRAIN COOLANT SYSTEM, THEN SAFELY RAISE SUPPORT CAR ON JACK STANDS. MAKE SURE VECHICLE SITTING ON SOLID LEVEL GROUND, WITH EMERGENCY BRAKES APPLIED YOU NEED TO DISCONNECT HEATER CORES HOSES FROM UNDERNEATH VECHICLE ******* THEN YOU HAVE TO FIRST OF ALL DISABLE AIRBAGS,FIRST TURN OFF RADIO , THEN REMOVE NEGATIVE BATTERY CABLE WAIT 20 MINUTES BEFORE WORKING AROUND DASH AREA. THIS ALLOW AIRBAG TIME TO DISCHARGE. REASON YOU NEED TO DISABLE AIRBAGS BECAUSE YOU HAVE AIR BAG IN THE DASH ON PASSENGER SIDE AND AIRBAG IN THE STEERING WHEEL.TO REPLACE HEATER CORE YOU HAVE TO REMOVE RADIO TO REMOVE HEATER COVER CLIPS AND THE FLOOR SHIFT CONSOLE HAS TO BE REMOVE SO YOU CAN REMOVE HEATER CORE BOTTOM COVER SCREWS SO YOU CAN DROP HEATER CORE FROM THE BOTTOM OF DASH BELOW FLOOR SHIFT CONSOLE AREA. REMOVE TRANSMISSION SHIFT KNOB YOU HAVE A LITTLE RETAINING CLIP YOU CAN REMOVE CLIP WITH SMALL FLAT HEAD SCREW DRIVER. TO REMOVE SHIFT CONSOLE OPEN ARM REST PART LOOK DOWN IN THE BOTTOM ARM REST YOU WILL SEE BOLTS HOLDING CONSOLE IN PLACE.
